OSCREEN(1)OSCREEN(1)
NAME
oscreen - redirects mouse and keyboard to remote screens
SYNOPSIS
oscreen [ -a name=address ] [ machine ... ]
DESCRIPTION
Oscreen is a omero(1) user interface for both mousefs(4) and
kbdfs(4). It permits the user to click on a machine (actu-
ally, a display) name to redirect both keyboard and mouse to
that machine. Both devices are reclaimed back for local
usage by pressing mouse button 1 near the up-left corner of
the screen.
To perform its job, oscreen writes to the /dev/mousectl file
to issue mouse redirection requests. The keyboard is redi-
rected as a result of mouse redirection.
The program uses env/terms to determine the list of machines
involved and the address for their mouse redirector, when no
machine name is given in the command line.
Events in the interface makes the program refresh the list
of machines.
The option -a can be used to add additional screen names to
the interface. The argument contains a screen name, an equal
character, and the network address where to reach mousefs
for that screen. The program assumes that kbdfs can be
reached at the same address but using the next port in
numeric order.
EXAMPLE
/rc/bin/brc runs this to support user I/O redirection:
kbdfs -V /dev/kbd
mousefs -V /dev/mouse
Later, the user runs this within a omero session:
oscreen
Now the user can click on a machine name to command its win-
dow system, and click at the top-left corner to reclaim the
input devices back to the local system.
